While loop

Question

Hello guys , can anyone tell me what is the "while" loop function in python and how to use it.

Answer 1

In the python courses, it is explained that the "while loop" is used when you don't know the exact number of times the loop must run, and this is the main difference with the "for loop", which needs an exact number of times to run. Two ways to loop based on the situation you are facing. Study the three python courses and you'll find plenty of information.

Answer 2

Ruben ,

be careful when saying about a for loop:

... which needs an exact number of times to run ...

you can exit a for loop at any time with a break statement.

Answer 3

The while loop in Python is used to repeatedly execute a block of code as long as a condition is true. Here’s a simple example:

count = 0
while count < 5:
print("Hello")
count += 1

In this example, the while loop will print "Hello" as long as the value of count is less than 5. With each iteration, count increases by 1, and once it reaches 5, the loop stops. This is useful when you want to repeat certain actions until a specific condition is met.
